Displays for information, pricing & promotions
Digital signage uses electronic displays to present information, advertising, prices, announcements or visual content. It can use an LED video wall, a scrolling display or another suitable screen. Content can change without replacing the physical sign.
Halo Technologies supplies, installs, configures and supports LED signage solutions from Kattappana, Idukki, Kerala. We help select the display and control system around your application, viewing distance, environment and content requirements.
Digital signage describes the use of the display. The display technology determines which content it can show and how it fits your space.
A modular LED video wall combines panels into a larger display. It is a form of digital signage when used for promotions, video or information, including commercial and event applications.
Dimensions depend on the panel arrangement. Pixel pitch is the spacing between display pixels: closer viewers generally need finer pitch for readable detail. Brightness must suit ambient light, with equipment selected for indoor or outdoor use.
A scrolling LED board presents short text such as notices, offers, opening information and announcements for businesses or institutions. A single-colour board shows messages in its supported LED colour; it is not a full-colour video screen.
Halo's documented P10 installation used a red horizontal board and a yellow vertical board. The configuration and text size should suit the available space and where people read it.
Price boards show changing numeric or text information for applications such as retail counters, supermarkets and petrol pumps. Their layout should keep the relevant price or message clear.
Suitable systems can support remote or multi-branch price updates. The controller, network connection and update requirements must be agreed for the selected system.
A digital-signage system combines a message, a compatible player or controller, and a display. The player may be separate, built into the screen or part of the LED control system.
Update methods depend on the system. In Halo's P10 project, a compatible mobile application connected to the HUIDU controller's local Wi-Fi for message updates. Local Wi-Fi updating does not itself mean internet or cloud control.
Remote updates and scheduling need compatible hardware, software and, where applicable, a suitable network connection. For multiple sites, discuss who changes the content, access permissions and whether each site needs different messages.
Choose around how often the message changes and where it will be seen. A long-term static sign and a frequently updated display have different practical needs.
Swipe or scroll across the table to see both options.
| Factor | Digital signage | Printed signage |
|---|---|---|
| Content changes | Electronic updates using the selected control system. | Requires changing or replacing the printed material. |
| Motion and video | Available on suitable displays; text boards have different capabilities. | The printed message stays static. |
| Scheduling | Possible with compatible software and hardware. | Changes normally require physical intervention. |
| Initial investment | Often higher because it includes electronics and installation. | Often lower for a simple sign; size and construction still matter. |
| Frequent updates | Changes can reuse the existing display. | Repeated changes can involve reprinting and fitting costs. |
| Ongoing needs | Power, content management and equipment maintenance. | Cleaning, condition checks and eventual replacement; illuminated signs also need power. |
Location affects readability, equipment selection and the installation. Brightness alone does not establish that a display is suitable outdoors.
Check the nearest viewing position, ambient light and reflections. A screen behind glass can still face strong daylight and heat. Match pixel pitch, text size and brightness to the audience and the message.
Allow for ventilation, power and data connections, mounting and access for maintenance.
Consider sun exposure, rain, moisture, wind and viewing distance. Select equipment and an enclosure suited to the actual weather exposure, with protected connections and an appropriate mounting structure.
Plan power requirements, brightness settings, drainage or ventilation as applicable, and access for servicing. Environmental specifications must be checked for the selected equipment and installation.
Bring these details to the first discussion. A useful system fits the message, viewing conditions and how your team will operate it.
Short notices may suit a scrolling board; changing prices may suit a price display; richer visual content may suit an LED video wall. LCD screens are another display technology to compare for close-range detail. Our LED versus LCD retail guide explains the selection considerations.
For technical background, see LG's explanation of modular LED displays and Samsung's guide to pixel pitch, resolution and viewing distance.
A quotation depends on the selected system and site requirements. A screen dimension alone is not enough to price the completed installation.
Share the application, location, dimensions and control needs so we can discuss the scope. Confirm what the quote includes and the support arrangements for the chosen system.
Halo's display service covers supply, installation, configuration and local support. The actual work depends on the display and the site.
For ongoing use, keep content readable, check that updates and playback work, and allow access for equipment service. Outdoor installations also need attention to the condition of their enclosure, mounting and connections. Discuss the maintenance needs and support terms for your installation with the team.
A real Halo display installation
Halo Technologies assembled and installed two outdoor single-colour scrolling boards near New Bus Stand: a horizontal red display and a vertical yellow display. The case study documents rear-side sealing, workshop testing, installation and local Wi-Fi message updates with original photographs and footage.
This is an example of a text-display installation. The configuration for a full-colour video wall or another application will differ.
Halo Technologies serves Idukki and surrounding areas, subject to project requirements. Share your location, intended content, approximate display size and whether you need local or remote updates.
